Question

Which statement is accurate in regard to secondary hypertension?

1. There is no known cause.
2. It can result from chronic renal impairment.
3. It is also known as idiopathic.
4. It accounts for 90% of all hypertensive cases.

Answer 1

Secondary hypertension can result from chronic renal impairment, and it represents about 10% of all hypertension cases. It is not idiopathic, as it has a known cause, unlike primary hypertension.

Step-by-step explanation:

The accurate statement in regard to secondary hypertension is that it can result from chronic renal impairment. Secondary hypertension is caused when another medical condition or medication leads to high blood pressure, as opposed to primary hypertension, which is high blood pressure without a known secondary cause. Conditions such as chronic kidney disease (CKD) or endocrine disorders like Cushing's disease can lead to the development of secondary hypertension. This form of high blood pressure accounts for about 10% of all hypertensive cases, not 90%. Therefore, statements 1, 3, and 4 are incorrect.
